Dash harness for 2001 Toyota Tacoma

Hello I have a 2001 Toyota Tacoma 3.4L 5pd Mt 4x4 I am looking to buy a dash harness for it ,I bought the truck when it was basically abandoned and rats got in it and ate all the dash harness (I didn’t know ) I’ve bought 2 harnesses already and they did not did fit they are slightly different and the bad thing is I can’t look at the part number since the rats are the tag too so I can’t really look for by the part number I’ve tried calling Toyota and using the VIN and they told that won’t help and that I need the part number any body got an idea what I can do?, My mechanic tried to look at it to fix it but he said it’s damaged in too many parts it’s not savable
